i was riding some backroads, stopped at a gas station for a drink. Heard a hissing sound by my bike. Found the end of a nail in the tread on my rear tire. So i fixed it with one of those gooey plug things that you stick in the hole with that t shaped piece of metal. It sealed up and i inflated it with fix a flat. About how long do you think those plugs last in there. Am i safe to ride on it for awhile, or should i buy a new tire right away. I would have bought a tire today, but i got laid off this morning and i encountered the nail on the way to look for another job. Talk about a shitty day.!!!
